Red Skull should do well here. He was pretty much Cap but with a meaner attitude. That said, WS had more impressive feats so i'd go with WS. Good fight though.

Not even sure Red Skull would get any significant hits in. He fought a Cap that was quite the noob combatant. Winter Soldier Cap would wreck Skull and so would Bucky.
